This tutorial assumes that you already know how to annotate.
To get an embossed effect, you layer different colored text over each other offsetting the layers. The offset and the number of layers depands on the size of the image and the fatness of the font. With bigger images and fat fonts you can offset by 2px and use 3 layers. For midsized images, you may or may not want three layers and you can use 2-3px offset depending on how fat the font is. For small images use only one layer with 1px offset.
Offset = 1px
One layer
Offset = 2px
Two layer
Center your main layer first. Many fonts will not look centered vertically when you tell ImageMagic to center the text. For some larger banners I had to offset the text -5px to center it. Once you figure out what your offset needs to be, make a note of it and back up to the beginning.
White layer. If it looks like light is hitting yout image on the upper right corner, offset your white layer down and to the left.
Gray layer. This is the one you leave out if your image is small or your fonts are skinny. Offset it towards the same side as the light seems to be hitting your image. If the light is hitting the upper right corner, offset the gray layer up and right.
Black layer. This is the main layer. Offset it the amount determined in step one.
The close up below is of a 2 layer, 2px offset emboss.
